Weidman is one of nine fighters in UFC history to earn a knockout stemming from a standing elbow strike. He accomplished the feat against Mark Munoz at UFC on FUEL TV 4.

Weidman’s 68.2 percent takedown accuracy is the second best in middleweight history and the fourth best rate overall in UFC history.

Weidman’s average of 4.21 takedowns per 15 minutes of fighting is the highest rate among active UFC middleweights.

Weidman has only been controlled by his opponents for a total of three seconds in the clinch and on the ground throughout his UFC career, the shortest amount of any fighter in UFC history with a minimum of five fights.

Machida headlines a UFC card for the eighth time in his career. To date, he’s 4-3 in UFC main events.

Machida, a former UFC light heavyweight champion, will have the opportunity to become just the third fighter in history to win a title in more than one weight class. The only others to have accomplished the feat are Randy Couture and B.J. Penn, who, coincidentally, Machida holds career victories over.

Machida has earned eight career victories against fighters who once held a world championship in UFC, Strikeforce or PRIDE.

Machida competes for the third time since dropping to the UFC middleweight division. “The Dragon” outpointed Gegard Mousasi over five rounds at UFC Fight Night 36 and stopped Mark Munoz with a first-round knockout at UFC Fight Night 30.

Machida stopped Munoz with a head kick, a strike that led to the 12th knockdown of his UFC career, which is the fourth most in history behind Anderson Silva (17), Chuck Liddell (14) and Melvin Guillard (13).

Machida has earned head-kick finishes over Munoz and Couture, making him one of just seven fighters in UFC history to stop two opponents with a kick to the head. Vitor Belfort, Donald Cerrone, Daron Cruickshank, Yves Edwards, Anthony Johnson and Paul Taylor are the others.

Machida landed 65 percent of his takedown attempts during his UFC light-heavyweight career, which is best rate in divisional history. Machida’s 81.8 percent takedown defense rate at 205 pounds ranks third in divisional history.

Machida absorbed just 1.41 significant strikes per minute of fighting in 205-pound competition, the third lowest rate in UFC light-heavyweight history among fighters with a minimum of five bouts.
